• The 12MB777 is a very high sensitivity (101.5 dB 1W/1m) midbass driver with high power handling capabilities. It can be used as either a bass/mid driver in compact 2-way reflex enclosures or as a direct radiating or horn loaded, dedicated midrange driver, in multi-way touring and fixed installation concert and arena systems. Its curvilinear paper cone made from a special high strength wood pulp, has been designed to achieve the best possible linearity within its intended frequency range.
• The cone is carried by a multiroll suspension formed of a linen-like material, which is more resistant to aging & fatigue than traditional materials. The 75 mm diameter state-of-the-art voice coil is similiar to those fitted to our top-of-the-range 18-in and 15-in models but it is wound w/ aluminum wire. It employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer & inner surfaces to achieve a mass balanced coil.

The 75 mm diameter state-of-the-art voice coil is similiar to those fitted to our top-of-the-range 18-in and 15-in models but it is wound with aluminum wire. It employs our Interleaved Sandwich Voice coil (ISV) technology in which a high strength fiberglas former carries windings on both the outer and inner surfaces to achieve a mass balanced coil. This results in an extremely linear motor assembly with a reduced tendency for eccentric behavior when driven hard. The excellent performance capabilities of this loudspeaker are further enhanced by the Double Demodulating Rings (DDR) designed to dramatically reduce the intermodulation and harmonic distortion and improve transient response.
